Commercial Lease Types

Triple Net (NNN)

Tenant pays base rent plus property taxes, insurance, and maintenance (CAM). Most common for retail and industrial.

Full Service / Gross

Landlord covers all operating expenses. Rent is higher but predictable. Common in office buildings.

Modified Gross

Shared expenses — landlord covers base year costs, tenant pays increases above that.
